Liquid ammonia is a colorless aqueous solution with a pungent odor that is used as an acidity regulator.
Ammonia gas is converted to liquid under pressure of 125 psi (862 kPa) to be used for various purposes. Like other gases, the solubility of ammonia decreases with increasing solvent temperature, and the density of ammonia solution decreases with increasing concentration of dissolved ammonia. At higher temperatures, the purity of the saturated solution decreases and the density increases. After heating saturated solutions, ammonia gas is released.

Environmental impact of Ammonia
Today, they are trying to reduce the pollution of greenhouse gases such as ammonia from the planet. In general, the harmful effects of NH3, as a toxic substance affecting the environment, cannot be ignored. When this substance is in the vicinity of other chemicals, irreparable damage may occur to humans.
Handling and Storage of Ammonia
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Separate from incompatibilities. Store below 25 C. Protect from direct sunlight. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.
Packing
Ammonia Solution is supplied in varying packaging capacities ranging from 5 liters to 235 liters HDPE plastic containers, 6 MT to 15 MT tankers and 22 MT isotank.
